fix(module): only parse global components

[farnabaz]

resolves #50

[farnabaz]

I don't understand why slots are not detected when I filter global components

codes are exactly same in both cases:

component.fullPath /Users/far/projects/nuxt/nuxt-component-meta/test/fixtures/basic/components/global/TestContent.vue 
slots: [
  {
    name: 'title',
    type: '{}',
    rawType: undefined,
    description: '',
    schema: { kind: 'object', type: '{}', schema: {} }
  },
  {
    name: 'default',
    type: '{}',
    rawType: undefined,
    description: '',
    schema: { kind: 'object', type: '{}', schema: {} }
  }
] 
<template>
  <div>
    <h1><slot name="title" /></h1>
    <slot  />
  </div>
</template>

<script setup>defineProps()</script>

filtered

component.fullPath /Users/far/projects/nuxt/nuxt-component-meta/test/fixtures/basic/components/global/TestContent.vue 
slots: [] 

<template>
  <div>
    <h1><slot name="title" /></h1>
    <slot  />
  </div>
</template>

<script setup>defineProps()</script>

@Tahul do you have an idea about it?

We need to find a solution for this

[Tahul]

Looking into it :)

I think this should be configurable

Issue is fixed and tests are passing; merging this.

I added the feature behind globalsOnly option that can be enabled from the module config.
